Can Anyone Identify This Boston Machine Cancel?

Hello All,
I've come across this Boston machine cancel pictured below. It is some sort of International machine cancel or some other type? I haven't seen one before with horizontal bars in this pattern and so close to the CDS.
Thanks, Will

I think I found another example here:

wt1: thanks! jaywild doesn't identify the machine type except it's Hanmer #13. Anyone have a U.S. Machine Postmarks 1871-1925 by R.F. Hanmer handy? I'll message the seller as well.

I read the link as being an "American (Postal Machines Co.)" machine cancel. In fact, here's a selected paragraph from The Boston Post Office and the Evolution of Machine Cancellation (an Exhibit by Wm. P. Barlow, Jr., Gold Medal at INDYPEX 2008):

On another matter, the postal card addressee is one E.B. Buckingham, Colchester Street, Brookline, Mass.

I did a little research and found that E.B. Buckingham was, in fact, Edwin B. Buckingham, President of the American Tube Works, located in several spots in Boston (and later) Somerville, Massachusetts.

Here's a period ad on the back of one of their envelopes:




And this is a more contemporary commentary on the firm after their later move to Somerville, MA:

wt1: Nice research! And you're right, it's an American Postal machine cancel. I didn't realize it given the way it was worded in the ebay description, but it makes sense now. Jaywild (the seller) messaged me and confirmed that all the postmarks he's selling this week are American Postal machine cancels.

...and while we're chatting about Boston cancels. Here's two more I've come across recently:

A Leavitt machine cancel



A fancy hand cancel with negative 11

Nice cancels!

Love it! I admit that I never seen one exactly like that before? Thank you!

I have a copy of the Second edition of Hanmer's book, but I'm not 100% sure how to interpret it. This looks like either a type 14, 15, or 16 American bar cancel. Type 13 does not have a complete vertical bar.

Personally, I think it looks most like a type 16
